What to do if my Shindaiwa 490 spark plug has no spark?

If there is no spark at the spark plug of your Shindaiwa Chainsaw, check the spark gap and adjust it to 0.6 to 0.7 mm. Also, the spark plug may be covered with carbon or fouled with fuel, so try to clean or replace it. If the spark plug is defective, replace it.
